pH-meter for Industry - OpH228
OrigaLys


pH-meter designed for teaching and laboratory use by a company founded by former Radiometer engineers. Interface fully compatible with old Radiometer pH-meters.
Calibration on 1 to 3 points between two sets of buffers (IUPAC or 4-7-10). Free mode available for manual buffer adjustment. Previous calibration settings can be reused.
Calibration settings stored in instrument. Export to .txt file via USB. Compatible with almost all Ex.A.O. systems:
Manual mode (continuous reading with stability indicator) or automatic mode (freezes at 100% stability).
Single or combined electrode via BNC plug. Reference electrode via 4 mm banana plug. Temperature sensor via CINCH input. Manual temperature entry possible.
